The dotnet/iot repo is getting multiple updates of arcade per day (parallel PRs)

This has so far happened two days in a row. Yesterday's two PRs were:
https://github.com/dotnet/iot/pull/652
https://github.com/dotnet/iot/pull/653

[mmitche]

This is almost certainly because of #3595. For repos getting multiple updates, we are retrying requests while the rate limit has been exceeded, which runs over the timeout on the update operation. We lose track of the PR we were opening, then open another.

Happend once more time:
https://github.com/dotnet/iot/pull/665
https://github.com/dotnet/iot/pull/662

@riarenas 3 times in one week makes me feel that this is actually something we should probably look into. Would you be able to help us investigate?

@mmitche just sent out a PR that should help with #3595, which we believe is the main cause of the duped PRs.

Should be mostly unblocked by https://github.com/dotnet/arcade-services/pull/582

Haven't seen this happen again. Feel free to close this is you want and I can reopen if I ever see it happening again.
